The Role of Family Factors in the Development of Dental Anxiety in Children.

Background and Objectives: In the literature, the influence of parents who suffer from dental anxiety and a previous unpleasant experience at the dentist are cited as the two most common causes of dental anxiety in children. The aim of this study is to investigate the relationship between socioeconomic factors and the development of dental anxiety in children aged 9 to 12 years. Materials and Methods: A total of 131 children and their accompanying parents/guardians participated in the cross-sectional study. The children were divided into an experimental group, which visited a specialised office for paediatric and preventive dentistry for the examination, and a control group, which visited a primary care dental office. During the visit, the children completed questionnaires on dental anxiety (CFSS-DS). Parents completed a socioeconomic questionnaire and a dental anxiety questionnaire for adults (CDAS). Results: The results showed a statistically significant positive predictor: parental dental anxiety as measured by the CDAS. In addition, the t-test showed that children who visited a specialised dental office did not show a statistically significant increase in dental anxiety compared to children who visited a primary care dental office. Conclusions: With this study, we confirm the influence of parental dental anxiety on the development of dental anxiety in children. The socioeconomic status of the family and the type of dental office do not play a statistically significant role in the development of dental anxiety in children.

Measurement of the Dentin Wall Thickness of the Maxillary Central Incisor in Relation to the Stage of Root Development: A Pilot Study.

Objective: The aim of this study was to determine the average dentin wall thickness (DWT) of the maxillary central incisor (MCI) required for performing finite element analysis (FEA) models of root development. Material and methods: A total of 137 intraoral periapical radiographs of MCI in children aged 7 to 11 years were examined and then classified into 5 groups according to root development stages, which included 1/2 of root development (S1), 3/4 of root development (S2), more than 3/4 of root development (S3), complete development with wide-open apex (S4) and complete development with closed apex (S5). DWT was measured at three reference (horizontal) lines: at a distance of 1 mm from the apex (M), 4 mm from the apex (L) and at the cervical line (K). The distal dentin wall thickness (M1, L1, and K1), the pulp thickness (M2, L2, and K2), the mesial dentin wall thickness (M3, L3, and K3), and the apex thickness (N) were measured using the diagnostic software Soredex Scanora 5.1.2.4. Statistical analysis compared the values of the parameters K, L, and M between developmental stages (multivariate ANOVA) and the linear correlations between the parameters (Pearson's correlation analysis). All analyses were performed at significance level α = 0.05. Results: There were statistically significant differences between the developmental stages for parameters L and M, while no significant differences were found for parameter K. Most of the correlations between the parameters were statistically significant, with the values of the Pearson correlation coefficient R > 0.6 considered practically significant. All parameters on the same reference line for distal and mesial dentin wall thickness and for pulp thickness correlated well with each other (R = 0.46 - 0.68), but there was no statistically significant correlation with total root thickness on the same reference line (parameters K, L, or M), except for parameter K3 (R = 0.42). Conclusion: Despite the limitations of this study, the mean values of the selected parameters for the 5 groups of developmental stages of the maxillary central incisor could be used to model dentin wall thickness using finite element analysis.

Analysis of Hospital-Based Dental Procedures Under General Anesthesia in Uncooperative Patients: a Retrospective Study.

Background: General anesthesia is a well-documented therapeutic option for the provision of dental treatment, particularly in patients with special healthcare needs and uncooperative pediatric patients. Objectives: This retrospective study aimed to analyze the characteristics of dental general anesthesia (DGA) procedures for uncooperative patients of all ages in a tertiary healthcare facility, Clinical Hospital Dubrava, in Zagreb, Croatia. Material and methods: The hospital records for the patients treated for various dental reasons under GA were obtained at the Clinical Hospital Dubrava in Zagreb, Croatia. Results: Between 2014 and 2019, a total of 810 DGA procedures were performed including 607 patients. The median age was 18 years. Almost half of the patients referred to undergo DGA procedures were from the City of Zagreb and Zagreb County, 27.8% (N=225) and 21.0% (N=170), respectively. More than 90% of patients undergoing DGA procedures were referred with 1 to 3 medical conditions. 47.9% of patients had 1 to 3 dental conditions, of which caries was the most common condition (95.7%). The mean waiting time (±SD) was 113.06 (±62.62) days. 90 patients (14.8%) were referred for dental procedures under GA more than once, accounting for 203 procedures (25.1%). Conclusions: DGA remains a single dental treatment option for specific individuals. There is an institutional and, also, an organizational need to address the long waiting times and high repeated DGA rates.
